Question

2% of the computer chips manufactured by a company are defective. If 8 samples are picked at random,find the probability that 2 of them are defective. @agent0smith just to double check my answer..

Answer 1

Looks like binomial probability, P(X=2).

Answer 2

i got 0.009921 as my answer..

Answer 3

Show your work. It's binomial with
n=8
x=2
p=0.02
q=1-p=0.98

Answer 4

Seems reasonable, though, your value.

Answer 5

yep,i don't hv the answer from book..so,i decided to double-check my answer..\[p(x=2)=8c_2(0.02)^2(o.98)^6\]

Answer 6

Thank you @agent0smith

Answer 7

That looks right.

Answer 8
